Which of the following numbers will replace the question mark (?) in the given series?
5, 9, 25, 97, 481, ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 2881
Given series: 5, 9, 25, 97, 481, ?
The series follows this pattern:
5 × 2 - 1 = 9
9 × 3 - 2 = 25
25 × 4 - 3 = 97
97 × 5 - 4 = 481
481 × 6 - 5 = 2881
So, the next term in the series is 2881.
